Relationships Between Organisms:
Species interact every day. That interaction is a vital part of how organisms develop and change over time. When you study species, it is important to watch the way they interact with their surroundings.
Grade means HAVING SIMILAR ADAPTIVE PATTERNS.
In evolution, a grade refers to a group of species that have similar traits (the trait could be morphological or physiological) and which has given rise to another group that possess major differences from the ancestral form.

Answer:
B. A bridge-like connection is created between bacterial cells for genetic material to be transferred.
Explanation:
A. There is a change in the nucleotide sequence of a DNA molecule. - this is describing a genetic mutation
B. A bridge-like connection is created between bacterial cells for genetic material to be transferred. - this is <u>conjugation</u>, a type of genetic transfer between donor and recipient bacterial cells. It is a way that bacterial cells achieve genetic variation. For example, bacteria can share antibiotic resistance genes between one another. They do not directly contact one another, instead, they use a structure called a pilus to exchange material
C. A bacterial cell takes DNA fragments from a dead cell and incorporates them into their DNA molecule. - this is transformation, another type of genetic transfer where bacterial cells take up bacterial DNA from the environment. These molecules of DNA are usually from dead bacteria
D. There is a transfer of DNA from bacterium to another by a virus. - this is another type of gene transfer called transduction, where a virus takes genetic material from one bacteria to another.
Answer:
hope this helps, im sorry if it dosent
Explanation:
1-
An equation derived by the twentieth-century physicist Albert Einstein, in which E represents units of energy, m represents units of mass, and c2 is the speed of light squared, or multiplied by itself.
2-
The equation — E = mc2 — means "energy equals mass times the speed of light squared." It shows that energy (E) and mass (m) are interchangeable; they are different forms of the same thing. If the mass is somehow totally converted into energy, it also shows how much energy would reside inside that mass: quite a lot.
3-
Einstein's greatest equation, E = mc2, is a triumph of the power and simplicity of fundamental physics. Matter has an inherent amount of energy to it, mass can be converted (under the right conditions) to pure energy, and energy can be used to create massive objects that did not exist previously
4-
The change in mass is related to the change in energy according to Einstein's equation: ΔE = (Δm)c2. ... The energy corresponding to the mass defect is the nuclear binding energy, the amount of energy released when a nucleus forms from its component particles.
